Melody Generation Based on Thematic Development Method Using Pitch Class Set and Rhythm Complexity

Abstract

This research is to create a melody generation system. Instead of using Markov chain with individual music parameter probability control, the pitch class set theory is adopted instead of generating pitch. The generated melody consists of motive and thematic development with variation. In addition rhythm complexity analysis technique is introduced in the proposed system with the inverse LHL method, to generate the rhythm with the rhythm complexity input automatically. This system can be used for algorithmic composition, and two cases have been verified successfully.
